.T all w'wmiit may concern.

Be it knownthat vI,- RoBER'r W. lvY, a citizen of the United-States,residing at New London,:in the countyof Stanley and State ofNorthUarolinaj have `made certain new and useful 'Improvements inCottonllickers, of whichthe following is aspeciication.

My invention is an improvement in that class. of cotton-pickers in whichthe picking devicesproper are dirigible by hand, a portion-0f. themechanism being driven by means locatedfupon awagon or wheeled frame,the operators being seated upon platforms supported from the latter andmanipulating the i 5 fpicking: devices in-such manner as to bring .them-inrcxontact. with -the cotton held in the open: bollfs as the machineadvances, the 'bott V,iibei'ri .z thus extracted and carried back intoafsiita 5le receptacle.

Myinveii'timlA is more particularly an improvement upon'lthat forming'.the-Subj ect ot my 'Patent No. 568,351. In such former invention aseriesi of 'endless toothed belts Werecausedto travel on pulleysarranged in.

a tubular cott0n-receiver adapted t'o be held and manipulated manually,the belts being caused to travel constantly in one direction by means ofgearing connecting with apowerdriven-Shaft .and the..cotton beingcarried back to and betweentoothed bars, and thus crowded or forcedbackwardinto a suitable" receptacle.. In mypresent invention toothedbelts are caused to reciprocate instead-of cons tantl. traveling in onedirection, they being suitab y connected with a toothed frame which. isreciprocatcd by mechanism actuated from a power-driven shaft 'locatedupon the wagon-frame. Various advantages have been attained by myimprovement, as will hereinafter appear.

The two''chicfI 'partsvof' the same are'indica'ted by the "lett'ers A1 B.. I (Seeespecia'llyFigs. 2 vand 8.) As' indicated in Figs. 1, 3, and '7, these parts'areinclos-ed by aQsheet-metal casing 1, the tubular part A being attachedthereto at theoter endend extending backward to a pendent delivery.spout or mouth 2, through which'thecot'ton discharges into a receptacleorintofa tubular A conductor leading toa receptacle. j' Thepar't i" Breciprocates within the' partAji't bein for I' driven shaft 5, as willbe'further e'yxplain'ed.v` Y" The rear portion of its cylindricalliody't (see f' 5) is provided internallywitli longitu'- i' dmal groovesin which the arms 7 #ofthe-parti? i vided with rearwardly-curved teeth91.- l It f will be noted (see especially 8)1"t;hat'tlie`f arms 7 of theretractor B are 'similarly pro= vided with rearwardly-projecting teeth102- in a bearing 12, (sec Figs.4 3--an d.-7,)providedy at the rear endof the extensionA- :of the ref-.

upon which the operatorlis'supported and carried while manipulating thepacking:mech' anism now being described. The operatorholds thesheet-metal casing'il 4inthe hand .8,11 The arms 7 are secured attheirrear ends toa head 11, to which-the rod 3,'befoe-1eferredf if" to, isdetachably connected.E .Ther-.od slidesv ards 16,. which are fixedonaplatform 17,` forming-an attachment Of-wheeledvehicle and directs.the-front end of the receiver tn the o en bolls, and the pickingandretrac ingy evices extract the -cotton therefrom.

The means ,by .which this is yiinmet iiatlel Figs. 2,3-, 4, and 7 Thebeltsl agfethrce@ equidstmtiy fromjachother;asindicatdinjxio 'f Fig. 4.They run on pulle s 20, which are mounted rotatably on fixe axles, therear pulley beinv located in a slot near the middle oi' the tubu ar body6 of the receiver. Thus the outerrun of the ybelts is exterior tothebody 6, and the inner run is within the same.

The several belts are provided with forked spring-teeth 21, these beinapplied, however, only to such portion o the belts as enlo ters andpasses inward in the body 6. The

belts are caused to travelthat is, to reciprocate-b f means of rods 22,which, vas shown in ig. 7, are connected with the bars 7 of theretractor B. Thus the toothed bars i 5 7 are caused to advance or enterthe receiver A at the same time that the toothed portion of the beltsenters and passes-backward in the receiver A., It will be perceived (seeFig. 3) that the belts 19 are arranged in alinement I zo .with thetoothed bars 8, (see also Fig. 5,) the same'constituting a fixedattachment 'of the tubular body 6', while the toothed bars 7 of theretractor B are arranged circumfer- V.entially in grooves or spacesbetween the *a5 jbelts, and when pushed forward inthe receiver A theyextend nearly to the front end of the same-that is to say, to the shorttoothed bars 8, arranged at the mouth or outer lend of the receiver. Itwill now be 3o understood that if the mouth ofthe receiver A beheld incota'c'twith the cotton of an o en boll, the retractor B beingreciprocated,

t e teeth 21 ofthe belts 19 wil 'enter the cot- 'tonvand extract it fromthe boll'and carry it 3 5 into and backward in the receiver, where theteeth of the short bars 8a will prevent` it passing out .as the bel-tstravel forward, the teeth of the belts -then releasing orfreeing;themselves from the cotton, and at the same 4,6 time the teeth 10 of theretractor-bars 7 enwithin the meuth'of the receiver serves as a' primarymeans foi` holding the cotton when the toothed portions of the beltsagain travel 4 55 outward, and the retractor-bars extending far forwardand alongside the belts take hol of the cotton and carry it backward ateach reciproeation so that a constant stream of cotton travels throughthe receiver, one por- 6o tion crowding another until it is deliveredinto' thependent tube 2. The operation is effected with minimum frictionof the working parts. The teeth 21, attached to the belts,

are made ofspring-steel. of such thinness that they are adapted to bendand turn backward,

A trate a belt for this purpose counter a twig, limb, or stalk ofsufficient size 4 and riuidity to offer any serious obstruction.

It will be seen that the operation of the device, so far as the operatoris concerned, con sists in merely holding the mouth or open front end ofthe receiver A to the open boils,

and this is done rapidly and Without. great eiort. The. rotation of thecrank 4 imparts-- the required reciprocating movements to the retractorB andthe pickerfbelts, as hasbeen already sufficiently indicated.Itw'ill be seen, Figs. 1, 3, and 7, that the rear end-0f the bar 13,which is rigidly connected with the receiver A, is forked to adapt itfor attachnient to the crank-shaft 5, which is suitably supported andjournaled in a T-,head 22, having, as indicated in Fig. A9, a stem 23,that enters a socket formedin the lower end of the bar 14, that swin son the driven shaft 15. The stem 23 is hel in the so'cket by means ofscrew 24, which passes through an'arc-slot 25, formed in the bar'14.(See Fig. 7.) It is thus apparent that 'the picking -mechanism'proper-that'is to say, .the parts A B-'inay e turned horizontally bymeans of -this joint connection with the swinging bar 14, and

since the latter is free to swing in a vertical plane forward and backitis further apparent that I thus provide a universal joint between thepicking mechanism proper and the shaft 15. This enablesthe pickingmechanism proper to be manipulated in any direction wit out in anywayaffecti'ng the o eration of the reci rocating parts by whic thecotton is picke and carried backward. The crank-shaft 5 is driven by abelt 26, that runs on a pulley 27, keyed on the driven shaft 15, andthus revolving therewith. While I illus- I may in practice employ itswell-known substitute-to wit a shaft and bevel-gears.

From the foregoing understood that as the mac ine progresses slowlythrough the field alongside a cottonrow the several o erators carried onthe ina-l chine are enable to readily direct the gathering or pickingdevices to the open bolls without damage to the stalk'or plant or anyunopen boils, the pickingmechamsni bein operated automatically 4 anddoing its wor most effectively and extracting the cotton cleanly andperfectly, as by hand.

That I claim is- 1. A cotton-picking mechanism proper loo "des-cri nonit will be consisting of a tubular receiver having inte# rior,longitudinal, toothed ribs, a retractor comprising toothed bars arrangedand adapted to slide between the ribs of therecewer toothed endlessbelts arranged on the frontportion oi the receiver, their inner runsbeing within the longitudinal passage of .the receiver,` and devicesconnecting their outer ter, so that theirinnerruns niove forward'as.-tractor, substantially as escribed.

2. The combination, with a driven shaft and a bal*l pendent from andswinging loosely thereon, of cotton-picking mechanism comprising atubular receiver having a ri id bar extended rearward and connected Withthe aforesaid pendent barfa toothed retractor "adapted to reciprocateWithin the receiver, a

crank-shaft journaled in the lower end of the pendent bar, a 'rodconnecting the crank With `the retractor; and'meansor driving the saidcrank-shaft,' the'sarne bein operatively connectedwith the driven shat', as described.

' 3.. In cotton-picking mechanism of the class indicated', a receiver'cornprisin a tubular'body having internal lon itudlnal ribs Aspacedapart andprovided VWithteeth proecting reervvardr in the central passageof the receiver,` an a surrounding casing yto which the receiver pro eris secured, the same being 4. In cottonpicking mechanism of the classindicated, the combination with the tubular receiver, and belts Irunningon pul-V leys arranged in slots ceiver, of azretractor com rising a headand toothed bars extending orward therefrom, and rigid rods connectedWith the belts exterior to the receiver and extending rearward andconnected With the retractor whereby the belts and retractor areoperatedsimultaneously, the belts being caused to travel to carry cotton intothe receiver as the toothed retractor advances to` seizei-t,substantially as described.
